• Win Enterprises unveils Atom-based LAN gateway and compact SBC

  Win Enterprises unveiled a fanless “PL-82000” networking gateway with 6x GbE and 2x SFP ports based on an Atom C3000. It also launched a Raspberry Pi sized “MB-5000” SBC that runs Ubuntu or Win 10 on Intel Apollo Lake.

  We tend to forget Win Enterprises because as its name suggests, the company typically sticks to Windows-supported products. Yet, they have increasingly produced barebones products without listed OS support, such as the new PL-82000 networking appliance, as well as Linux supported systems such as the MB-5000 SBC announced back in June. (In 2017, we covered an Intel Bay Trail based MB-80580 SBC and Win IoT-380 Gateway with Linux support.)

• Raspberry Pi 4 PCI Express: It actually works! USB3, SATA… GPUs?

  Recently, Tomasz Mloduchowski posted a popular article on his blog detailing the steps he undertook to get access to the hidden PCIe interface of Raspberry Pi 4: the first Raspberry Pi to include PCIe in its design. After seeing his post, and realizing I was meaning to go buy a Raspberry Pi 4, it just seemed natural to try and replicate his results in the hope of taking it a bit further. I am known for Raspberry Pi Butchery, after all.

• Raspberry Pi 4 B+ - PCI Express

  Why did I do it? Because I wanted to see if it can be done. Because Raspberry Pi 4 might be the cheapest device that is PCIe capable after a relatively minor modification (if I didn't lift the capacitors when desoldering the VL805, this is literally 12 soldering points). That, in turn, can be quite handy for developing own PCIe cores for various FPGA based experiments.

  I'm sharing it to allow people to learn from this - and to dispel the myth that PCIe is somehow out of reach of hobbyists due to some concerns over signal integrity or complexities. Stay tuned for more Pi4/PCIe experimentation!

It’s been a few years since developer Lukas Hartmann and designer Ana Dantes unveiled their plans for a DIY, modular laptop designed to run free and open source software.

Since then, the folks behind the MNT Reform project created a small number of early prototypes, introduced new hardware with beefier specs and some other improvements, and have begun producing prototypes of version 2 of the laptop.

Once everything is up to snuff, the plan is to launch another crowdfunding campaign for folks interested in purchasing their own MNT Reform 2 laptop — but since the design files will be open source, there’s nothing stopping anyone from downloading the necessary files and assembling their own (if they also want to go through the trouble of sourcing all the components including a custom PCB).

If you’re an electronics hobbyist, chances are you’ve heard of the Arduino. It’s a tiny computer that you can use to do surprisingly complex things. It also happens to be behind a fair number of Internet of Things projects.

While some people reach a for Raspberry Pi or something even more powerful, an Arduino or Arduino Uno might be all you need. We’ve put together a list of IoT projects that prove this to be true.

• Attaching a CPU fan to a RPi running Ubuntu Core

  When I purchased my Raspberry Pi4 I kind of expected it to operate under similar conditions as all the former Pi’s I owned …

  So I created an Ubuntu Core image for it (you can find info about this at Support for Raspberry Pi 4 on the snapcraft forum)

  Runnig lxd on this image off a USB3.1 SSD to build snap packages (it is faster than the Ubuntu Launchpad builders that are used for build.snapcraft.io, so a pretty good device for local development), I quickly noticed the device throttles a lot once it gets a little warmer, so I decided I need a fan.

• A reference architecture for secure IoT device Management

  One of the key benefits of IoT is the ability to monitor and control connected devices remotely. This allows operators to interact with connected devices in a feedback loop, resulting in accelerated decisions. These interactions are mediated by a device management interface, which presents data in a user-friendly UI. The interface also serves as a client to remotely control devices in the field. Device management is, therefore, a key component of IoT solution stacks, with a significant impact on the ROI of such deployments.

  However, there is no one size fits all when it comes to device management solutions. IoT solutions are deployed in various contexts. The purpose, the devices, and the users involved vary from one deployment to another, even within the same industry. It is, therefore, challenging to find a ready-made device management solution perfectly suitable to any given deployment.

  Security is the critical requirement that these deployments invariably share, for it must be implemented in line with the best practices. Secure authentication and communication encryption are indispensable for the management of mission-critical device fleets.
